Introduction
How can we use mathematics to express the way an object moves when it is speeding up? The velocity of the object is constantly changing, rather than a steady value. In this exercise, you will apply curve fits to graphs of position vs. time and velocity vs. time for a fan cart. You will use the curve fits to determine the parameters of the motion.
Objectives
In this experiment, you will
- Use video analysis techniques to obtain position, velocity, and time data for a cart that is speeding up.
- Apply curve fits to your graphs to determine how to mathematically describe the motion.
- [Extension] Analyze an additional video of an object undergoing constant acceleration.
Sensors and Equipment
This experiment features the following sensors and equipment. Additional equipment may be required.
